I decided to remove them and make shallow drawers ( about 3"deep) so the space will have six instead of three with the bottom one still being the original depth but I will cut the extra hight of the front to accomodate drawer #5. Hopefully this will allow me to see what I have, and find the tools I need.
I am cutting some of the pieces of the old drawers to reuse them in the new format but will have to make one new front as with the new congfiguration I can't get six fronts out of the existing ones.
If this works out, I might do the same with the right hand cabinet as at the moment it basically has only two shelves and a lot of wasted space.
More pics when I finish the job.
